 Still incomplete?  (Changes to generic files?)
 
 
+### 2016-12-14
+
+Based on commit 17f0f5acdcfb9181203ca9b6d8f8cbc64e5ce843, [[tschwinge]] tried
+to build with `--enable-languages=all,ada`, but both with `--disable-bootstrap`
+and `--enable-bootstrap` we run into:
+
+    [...]
+    make[3]: Entering directory '/media/erich/home/thomas/tmp/gcc/hurd/master.build/gcc/ada/tools'
+    ../../gnatbind -I- -I../rts -I. -I/home/thomas/tmp/gcc/hurd/master/gcc/ada -o b_gnatm.adb gnatmake.ali
+    error: "system.ads" has restriction No_Implicit_Dynamic_Code
+    error: but the following files violate this restriction:

+    error:   "prj-env.adb"

+(Partial) review of differences:
